Specification of Letters Patent.

Patented Jan. 29, 1907,

Application filed. May 1,1906. fierial No. 314,702.

T at whom, it may concern: 7 Be it known that 1, JOHN H. Dmnrcn, acitizen of the United States, residing at Celina, in the county ofMercer andState of Ohio, have.

the secured animal.

A still further object is tojprovide a clamping device which may bereadily replaced in the event of wear or breakage and to provide a postwhich is simple in construction, positive in action, and which is formedof very few parts, so that it cannot easily get out of order. With theabove andother objects in view he the invention consists of a posthavinga head provided with a passage therethrough, the side- Walls ofwhich are grooved longitudinally to constitute guides for lugs extendinglaterally from a clampingblock'.' One face of this 2 5 block isirregular in contour, soas to coact with'a correspondingly-shaped seatformed by the bottom of the opening to firmly clamp upon a strapinserted under the block. The head is so constructed, that the block canbe so readily detached therefrom for the purpose of replacing it, andmeans are employed where by the block can be ositively actuated withinthe longitudinal s ots, so as to clamp upon or release thehitching-strap.

The invention also consists of certain other novel features ofconstruction and combinations of parts, which will be hereinafter morefully described, and pointed outin the claims.

In the accompanying drawings isshown the preferred form of theinvention.

-In said drawings, Figure 1 isanelevation of the head of the post. Flg.2 1s a vertlcal. Fig. 3 1S asectlon showing a.por-.

section. j tion of one of the grooved walls in'elevation,

4 5 and Fig. 4 is adetail viewof the sliding jaw.

Referring to the figuresbyj characters of reference, 1 is a'post havinga head 2 formed with an elongated opening 3,'preferably rec tangular inform, and the bottom of this opening is preferably grooved transversely,

as shown at 4, said bottom constituting a fixed jaw, as Will behereinafter explained. Guide grooves 5 are formed longitudinally withinthe side walls of the opening'3, and slidably mounted within them arelugs 6, extending in opposite directions from thesides of a sliding jaw7, the lower face of which is serrated or of the grooved bottom 4 forthe purpose of clamping on a strap and holding it securely in position.This sliding jaw 7 has an overhanging .ear 8 thereon adapted to embracea stem 9, provided with a head ;10, which ex tends under the ear. Thisstem 9 has threads 1]., which engage the walls, of a passage 12, formedin the upper ends of the 'head 2, and a wheel 13 or other suitable meansis located its rotation manually. Oppositely-disposed grooves 14 areformed in the sides of the opening 4 at right angles to the grooves 5,and these grooves 5 and 14 communicate. By adjusting the jaw 7 so thatthe lugs6 register can be removed from the post because the grooves 5are sufficiently wide to permit'the lugs to slide therein.

jthe head, the lugs are slid Within the grooves 5 until the ear 8 comesinto contact with the stem 9. This ear is so shaped as to embrace thestem and partly overlap the head 10, and while in this position on thestem the lugs 6 register with the, guide-grooves 14. g It is thereforeobviousthat by rotating the stem the same will be screwed longitudinallywithin-the head, so as to cause the jaw 7 to move towardor away from thegrooved bottom 4.

When it is desired to secure a hitchingstrap within the post, the stem 9is rotated, so

the opening 3. The strap, is then inserted through the opening andbeneath the jaw 7, and by rotating the stem in the proper direction thejaw? willclarnp the strap against the grooved bottom 4 and hold ittightly in position. i As the jaw 7 has an irregular working face whichfits withina correspondingly-shaped bottom 4, it will be seen that theclamped strap cannot possibly be withdrawn after onoe being clamped inplace. Considerable importance is attached to the fact that the jaw isreadily removable for the purpose of replacing it with a new one or forrepairing it! Y The preferred form of the invention has been set forthin the foregoing description;

an irregular contour, so as to cooperate .with

upon the upper end of the stem to facilitate with the inner ends of thegrooves 5 said jaw Whenit isdesired to place the aw 7 within as to slidethe jaw 7 away from the bottom of but I do not limit myself thereto, asI am aware that modifications may be made therein without departing fromthe spirit or sacrificing the advantages thereof, and I thereforereserve the right to make such changes as fairly fall within the scopeof the invention;

NVhat is claimed is. v

1. The combination with an aperturcd post having guide-grooves inopposite walls thereof, and transversely-extending grooves communicatingtherewith; of a jaw within the aperture and cooperating with one wall ofsaid aperture to form a clamp, projecting devices upon the j aw andadapted to travel within the guidegrooves, and means for sliding the aw.

2. The combination with an apertured post having guide-grooves inopposite walls thereof, and transversely-extending grooves communicatingtherewith; of a jaw within the aperture and cooperating with one Wall ofsaid apertureto form a clamp projecting devi'ces upon the jaw andadapted to normally travel within the guide-grooves, and rotatable meansfor sliding the j aw.

3. The combination with an apertured post having guide-grooves inopposite walls thereof, and transversely-extending grooves communicatingtherewith; of a jaw Within the aperture and cooperating with one wall ofsaid aperture to form a clamp, projecting devices upon the jaw andadapted to travel within the guide-grooves, rotatable means for slidingthe jaw, and said jaw detachably engaging the rotatable means.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
